AI Technical Summary
Existing dissolving devices are difficult to keep clean and sterile inside and outside the outer casing during aseptic operation, and are easily contaminated by bacteria in the air.
Design a drug dispensing device with dual air channels. Clean air is introduced into the inner and outer parts of the dissolving device through two independent air channel systems to ensure that bacteria do not adhere to the inner wall of the outer shell. A clean air unit is connected to the drug dispensing device to achieve aseptic operation.
It effectively prevents bacterial contamination of the inner wall of the dissolving apparatus, maintains the sterility of the drug solution, and meets the requirements of aseptic operation.
